Abstract
The utility model relates to an anti-bird rotating stab for a power transmission line, which is applied in that the high-tension transmission line prevents the bird trouble from triggering flashover trip and reduces an electric network suffering from the invading. The anti-bird rotating stab belongs to the technical field of electric power transmission. The technical scheme is as follows: the anti-bird rotating stab comprises a connecting ball (1), a bearing (4), a tubular arm (2), a reflector (3) and vertical needles (5), wherein the connecting ball is arranged on the bearing to rotate; one end of the tubular arm is arranged on the connecting ball, and the other end thereof is provided with the reflector; and the tubular arm is also provided with a plurality of vertical needles. The utility model has the following benefits: the anti-bird rotating stab further renovates the anti-bird thought; the advanced anti-bird-trouble idea, the delicate design and lower cost thereof provide an another effective means for the anti-bird-trouble work of the power transmission line; and the anti-bird rotating stab comes into use, and the trip-out rate of a major network caused by the bird trouble is zero. The anti-bird rotating stab aims at preventing the bird trouble in a straight-line wide-cross-arm iron tower with a 220 KV line, and can replace the comprehensive anti-bird effect of an anti-bird stab and an anti-bird stab row, and the effect is remarkable.
Description
Technical field
The utility model relates to a kind of anti-bird rotary thorn for transmission line, is applied to ultra-high-tension power transmission line and prevents that bird pest from causing the flashover tripping operation, reduces electrical network and is invaded and harassed, and belongs to electric power conveying technology field.
Background technology
At present, in recent years, along with the raising of social enviroment protection consciousness, natural environment is greatly improved, and adds the effective control of country to shotgun, make birds on kind and quantitatively, all increase in a large number, this embodies the harmony of nature and society, but for electrical network, the bird trouble on transmission line of thereupon bringing, particularly the insulator arc-over accident that causes of birds droppings constantly increases, the safe operation of frequent disturbance electrical network.Therefore, prevent that birds droppings from causing the electric transmission line isolator flashover fault, become the another new problem of transmission line accident prevention measure.In anti-bird pest is for many years explored, people used various means, comprise bird scarer (reflective mirror rotation), bird-scaring unit (light, sound unification), drive bird lacquer (color) etc., be installed on the shaft tower cross-arm, but after 1--3 month, birds promptly adapt to its existence, spend the laundering period after, birds are still movable on shaft tower.
Summary of the invention
The utility model purpose provides a kind of anti-bird rotary thorn for transmission line, has effectively controlled the generation of bird pest tripping operation, can not damage birds again simultaneously, solves the problems referred to above that background technology exists.
The technical solution of the utility model is: anti-bird rotary thorn for transmission line comprises and connects ball, bearing, pipe arm, reflective mirror, perpendicular pin, the connection ball is arranged on the bearing and rotates, one end of pipe arm is arranged on and connects on the ball, and the other end is provided with reflective mirror, also is provided with some perpendicular pins on the pipe arm.
Said pipe arm quantity is arbitrarily, preferably manages arms for three, and alternate 120 ° of layouts in same plane all are provided with reflective mirror and perpendicular pin on each pipe arm.
Said reflective mirror is the bowl-type glass mirror, and bowl is a stainless steel material.
The utility model also is provided with jockey, and the utility model is installed on the electric power line pole tower.
The clamp that the connection ball is made by thick walled steel tube and round steel is connected, the thick walled steel tube built-in bearing, after anti-bird rotary thorn is installed in shaft tower cross-arm top, the effect of bowl-type glass mirror wind-engaging power, drive the whole rotation of anti-bird rotary thorn, the light of formed solid space and reflection can prevent effectively that birds activity on shaft tower from not injuring birds.
The beneficial effects of the utility model: anti-bird rotary thorn has further been reformed anti-bird thinking, the design of its advanced person's anti-bird pest theory, exquisiteness and comparatively cheap cost provide another effective means for the anti-bird pest work of transmission line, anti-bird rotary thorn comes into operation, and major network bird pest trip-out rate is zero; The utility model is at anti-bird pest in the wide cross-arm iron tower of 220 kilovolt straight lines, and anti-bird rotary thorn can substitute the comprehensive anti-bird effect of bird-resistant and anti-bird row thorn, and effect is remarkable.
Description of drawings:
Accompanying drawing 1 is the utility model example schematic top plan view;
Accompanying drawing 2 is the utility model example schematic;
Among the figure: connect ball 1, pipe arm 2, reflective mirror 3, bearing 4, perpendicular pin 5, jockey 6.
The specific embodiment mode
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
Anti-bird rotary thorn for transmission line comprises and connects ball 1, bearing 4, pipe arm 2, reflective mirror 3, perpendicular pin 5, and the connection ball is arranged on the bearing and rotates, and an end of pipe arm is arranged on and connects on the ball, and the other end is provided with reflective mirror, also is provided with some perpendicular pins on the pipe arm.Said pipe arm quantity is three, and alternate 120 ° of layouts in same plane all are provided with reflective mirror and perpendicular pin on each pipe arm.Said reflective mirror is the bowl-type glass mirror, and bowl is a stainless steel material.The utility model also is provided with jockey 6, and the utility model is installed on the electric power line pole tower.
Installation is crossed in the making of the utility model embodiment: anti-bird rotary thorn is the stainless steel tube with three 600～650mm fixed length, steel pipe one side band bowl-type glass mirror (bowl is a stainless steel material), insertion and spot welding stainless pin are 9～10 on the steel pipe, every draw point 400mm height, the opposite side of steel pipe is welded in semicircle thin-walled steel ball (hollow), three steel pipe interval 120 degree are evenly arranged in same " disk ", the thick walled steel tube that steel ball passes through about a 150mm is connected with " clamp " that round steel is made, the thick walled steel tube built-in bearing, after anti-bird rotary thorn is installed in shaft tower cross-arm top, " bowl-type glass mirror " suffered wind-force drives the whole rotation of anti-bird rotary thorn, and the light of formed solid space and reflection can prevent effectively that birds activity on shaft tower from not injuring birds.At anti-mutually bird pest in the wide cross-arm iron tower of 220 kilovolt straight lines, anti-bird rotary thorn can substitute the comprehensive anti-bird effect of bird-resistant and anti-bird row thorn.
With reference to accompanying drawing, be the last plane anti-bird rotary thorn scheme of installation of shaft tower cross-arm.This figure bottom is for hanging the suspension insulator of lead, and the middle part is a cross-arm, is anti-bird rotary thorn in the middle of the top.The protective range of anti-bird rotary thorn is directly over the insulator string, and the protective range of anti-bird rotary thorn is a tower material around the insulator string, enlarges protective range.
